Morpower 3 way valve

[JAMMER]

If I was you I would replace all the O rings in the valve there is something leaking by. I have 2 of these valves but never used them yet. Maybe the O rings are the wrong material for oil use, the O rings could be the wrong size and letting oil go buy also the oil your using could be eating up or softening up the O rings. There are to many variables with out seeing the valve. Let me ask you this did the valve ever work right or was it likeb this from the start?? Ed
